WH l FFLETREE ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 426,227, dated April 22, 1890.

Application filed January 20, 1890- Serial No. 337,469. (No model.)

To all whom it may concern:

Be it known that we,D1nTR1on BAKENHUS and ALBERT MU EsELER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in lVhiffletree Attachments, of which the following is a specification,

The object of our improvement is to provide, for the purpose of securing the Whittletree to its support, novel means of simple construction which shall form a safe, strong, and durable connecting medium for the parts.

Our improvement is illustrated in the accompanying drawings, in which- Figure 1 is a broken View in perspective of a whiffletree connected with its supporting crossbar by our improved attachment; Fig. 2, a plan view of the attachment, and Fig 3 a section taken on the line 3 3 of Fig, 1 and viewed in the direction of the arrows.

A is the attachment, formed of two metal plates 13 and B and means, hereinafter described, for connecting them together and to the whifiletree and its support. The plate B, which may be of any suitable shape, though preferably that illustrated, is provided at one edge with a socket 0' and with ears q, extending therefrom and through which to secure the plate in place, and toward its opposite edge the plate B has a curved slot or guide The other plate B is provided at one edge with a perforated extension 0 or lip, from one side of which projects a perforated stud n, and near the opposite edge of the said plate is a perforated stud on, extending from around the perforation in a socket Z, formed on the adja cent edge of the plate, and from which eX-- tend laterally the cars 70, (like the ears q,) through which to secure the plate in place.

In practice we prefer to fasten the plate B to the whiffletree O and the plate B to the cross-bar D or other form of the support employed, though the two plates may be con versely applied. To secure the plate B, accordingly, in place, it is securely fastened to the whiffletree C, on adjust-ing it upon the under side thereof, with the slot 19 extending beyond the rear side of the Whiffietree and the socket r and ears (1 at the front side, as shown, by bolting it through. the perforated ears to the whiffletree, being additionally secured, if desired. The plate 13 is then secured to the crossbar D, on adjusting it upon the upper side thereof, with the socket Z and stud m extending beyond its rear side, by bolting it to the cross-bar through the perforated cars at the rear side of the cross-bar. W'hen thus secured to their respective supports by bringing the whifiletree and cross-bar together, the plates coincide in a manner to cause the stud n to enter the socket r and the stud m to enter the curved slot 1) and the two plates, and through the latter the whiffletree O and cross-bar D are secured together by a bolt 5, passed through the socket r and stud n and fastened by a nut t" and by a bolt 7L, passed through the stud m and socket Z and secured by a nut 7L. With the attachment thus ap plied, as will readily be seen, the draft exerted in the usual manner on the whifiietree is transmitted through the plate 13 against the studs 011 the plate 13, the bolts 2' and h being practically free from strain and serving mainly to connect the plates together. The curved slot p permits the proper extent of pivotal play on its axis (in the socket r) of the whitfletree whether the plate 13 or the plate B be uppermost or on the Whiffletree.

lVhile our improvement, constructed as illustrated and described, is especially adapted for use with a singletree, it is readily adapta' ble for a double or a treble tree.

The term plate herein employed with reference to the parts B and B is used generically, andis intended to include the mere marginal portion of each, since the metal it surrounds may be cored out in the casting for the sake of lightness and saving; or the plate maybe hollow, consisting merely of the marginal portion provided with the features of construction described. Obviously,furthermore, the socket a" and curved guide p may be respectively near the rear and front edges of one plate to coincide with the studs n and m, and then respectively near the rear and front edges of the other plate.

What we claim as new, and desire to secure by Letters Patent, is

1. In combination, a whifiietrec C, its sup port D, and an. attachment A, secured between and conncctin g the whi'lfletree pivotally to its support, and comprising a plate provided with a curved guide p and a socket r, and a plate provided With a stud m, engaging With the said guide and with a stud n, entering the socket r, the said plates being bolted together through the said socket and its contained stud and through the said stud m and guide p,-substantially as described.

2. In combination, a Whiflietree O, a plate B, having a curved guide-slot p near its rear end and a socket "r and ears (1 near its forward end and secured to the front side of the whifiietree through the said ears, a support D for the Whiffletree, a plate B, having near its forward end a stud n, entering the socket o", and near its rear end a socket Z, provided with a stud m, entering the guide-slot p and ears 7c and secured to the rear side of the said support through the ears k, a bolt 1', ex-

tending through the socket 7' and stud 'n and secured, and a bolt h; extending through the guide-slot p, stud m, and socket Z and secured, substantially as described.
